How you can persist login session in iOS Safari PWA (Add to House Display) with React and Node.js?

I’m constructing a PWA with React (frontend) and Node.js/Specific (backend).
On login, I save a JWT token in localStorage. I additionally tried utilizing cookies with cookie-parser and express-session.

This works high-quality in Android/Chrome:

• After I add the app to the house display, open it once more later, the login session remains to be legitimate.

However in iOS Safari (PWA added to residence display):

• After logging in, the token is seen in localStorage inside Safari.

• However once I launch the app from the house display, the token is lacking and the person is logged out.

Minimal Instance

Frontend (React)

// login.js
perform login() {
  fetch('/api/login', { methodology: 'POST' })
    .then(res => res.json())
    .then(({ token }) => {
      localStorage.setItem('token', token);
    });
}

// app.js
const token = localStorage.getItem('token');
console.log('Token on load:', token);

Backend (Node.js/Specific)

const categorical = require('categorical');
const cookieParser = require('cookie-parser');

const app = categorical();
app.use(cookieParser());

app.publish('/api/login', (req, res) => {
  const token = 'abc123'; // faux for instance
  res.cookie('token', token, { httpOnly: true });
  res.json({ token });
});

app.hear(3000);

Drawback

• In iOS Safari PWA home-screen mode, the session/token doesn’t persist.

• In Android Chrome, it really works as anticipated.

Query

• Is there any option to persist login/session when an iOS PWA is opened from the house display?

• If not, what’s the beneficial workaround?
